Where in the body are most abdominal aortic aneurysms (AAAs) located?

Most AAAs begin below the renal arteries and end above the iliac arteries. The size, shape, and extent of AAAs vary considerably. Like aneurysms of the thoracic aorta, AAAs may be broadly described as either fusiform (circumferential) or saccular (more localized). However, these descriptions represent two points on a continuum, and lesions that fall between the two points exist.
